We are finally coming back to the capital! Join GitHub Engineers **Marco Celon** and **Vic Perdana** as they demonstrate how to harness your workflow and explore how developers boost productivity with AI, reduce friction, and accelerate innovation, all while keeping control and quality in your hands. **Agenda** 5:30 - Pizza and networking 6:00 - Talk 6:40 - AMA 7:00 - Finish Please make sure to register for the event as we need to provide contact details to Microsoft for security purposes. Registration will close 48 hours prior to the event to provide enough time to send out the access passes for in-person attendees, but you can [join online](https://aka.ms/aotearoanzgithub/stream) on the day. If you have a topic you'd like to present (or hear about) please reach out, or create an idea in our [GitHub Ideas discussion board](https://github.com/orgs/NZ-GitHub-UG/discussions/categories/ideas).

Join GitHub Engineers **Marco Celon** and **Vic Perdana** as they take a deep dive into GitHub Copilot’s evolution from autocomplete to an agentic AI partner. Learn about MCP, A2A, and orchestration patterns shaping the future of agent workflows. They will also be an opportunity to ask your curly GitHub and/or AI Agent questions. **Agenda** 5:30 - Pizza and networking 6:00 - Talk 6:40 - AMA 7:00 - Finish Please make sure to register for the event as we need to provide contact details to Microsoft for security purposes.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

On Thursday, March 12, 2026, we will meet at the TEKSystems offices at 700 N Hurstbourne Pkwy. Doors will open at 6:00 p.m., and the presentations will begin sharply at 6:30 p.m. Along with an excellent presentation, TEKsystems will provide food. Please RSVP so we know how much food to order. Afterward, we will go to Brick House Tavern for drinks and food to continue the conversation. The session will also be broadcast at https://twitch.tv/TaleLearnCode. ### Much Ado About Nullable - C# Nullable Reference Types Explained In 2019 (C# 8.0) Microsoft introduced a feature that has generated a lot of confusion, debate and outright dissent. I'm talking about Nullable Reference Types. In this presentation, I we dig into this feature, explore why it exists, what problem it tries to solve, how it works, and how people have critiqued it, so that you as a programmer can decide if and how you want to use it.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

Come out to Improving for our monthly iOS and Mac meetings. This Month's Presentation: Nothing yet. (You should volunteer). What is Cocoaheads (http://cocoaheads.org/)? CocoaHeads is a group devoted to discussion of Apple Computer's Cocoa Framework for programming on MacOS X and iOS (including the iPhone, iPad and Apple Watch). During monthly meetings, members present on their projects and offer tutorials on various programming topics. What is BuckeyeCocoa (http://buckeyecocoa.org/)? BuckeyeCocoa is a group of Objective-C/Swift developers/enthusiasts. We host monthly Cocoaheads and near-weekly NSCoder meetings in Columbus, Ohio. The meetings are free to attend. Presentations! Presenters welcome! We are always in need of people willing to present material. Any Swift and/or Objective-C related topic is welcome. Times can be 5 minutes (i.e. lightning talks) to a maximum of 2 hours. Interested? Contact info is on the BuckeyeCocoa website. To volunteer for a presentation contact us at @BuckeyeCocoa on Twitter. Follow us on Twitter! @BuckeyeCocoa (https://twitter.com/#!/Buckeyecocoa/) For more information: http://buckeyecocoa.org/

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm
